I'm trying to remember where I read about the BAe senior engineer who was sacked after refusing to sign the relevant part of the MRA4 bid. IIRC, he felt that the project had been hugely underbid, & was far more complicated & riskier than the bid made out. He was replaced with someone who'd do as he told, whatever his private thoughts.... it's interesting watching the references to how badly managed the project was. I think going to P8 instead of MR4 would be a big leap forward in terms of capability and reliability.

He was right, of course. Some of the specific issues he'd said hadn't been properly assessed (e.g. the precise state of the old airframes) came back to bite. If they had been, I suspect that new-build aircraft would have been seen as more sensible.
I think that there's been a lot more mismanagement since, because those issues were tripped over fairly early on. I've heard rumours about the combat system & integration. Meanwhile, CASA/Airbus Military has bid for, won, & completed a contract to modernise P-3s for Spain, & is delivering the aircraft for a similar contract for Brazil, with relatively small cost & time overruns. Strip down & re-life the airframes (some new structural components needed in both cases) refurbish engines, fit an entirely new combat system, sensors, cockpit, etc. Total cost for 13 upgrades ca 15% of the MRA4 project.
